The behavior of the composite slab is conditioned, mainly, to the interaction that exists between the concrete and the steel deck, the shear connection between these two materials is provided by the chemical and mechanical adherence that exists at the interface of the materials that make up the slab. For the study of this property, a series of full-scale slab tests have been carried out, such as bending tests to identify the slipping load, which is directly related to the shear bond strength of the slab and which can be seen in the history of behavior under bending loads. Likewise, longitudinal direct shear tests (Pull-out) have been carried out on pieces of the slab to quantify the adherence through the maximum load applied at the interface. The study of the shear bond strength is very important because in most cases, the geometric conditions of the section and the slenderness of the slab will lead to this type of failure. For this reason, this research will be in charge of studying this failure condition, based on previously full-scale slab tests and new constructed specimens, in order to cover as many situations as possible. The results of the tests, such as the slipping load and the deflection in which it occurs, will allow establishing a new relationship between the slipping load, the geometric and mechanical parameters. This new relationship will be carried out for each of the steel deck profiles under study and this formulation will be validated as an alternative proposal to the “m y k method“, which allows calculating the slipping and functionality load because these values are very useful for the verification and design of this type of composite slabs. Additionally, a study related to the shear bond stress will be presented, which was obtained from the relative displacements, between the concrete and the steel deck, measured at the end of the slab and simultaneously to the bending test. The shear bond stress will be determined from analytical methods and will help to better understand the behavior of the slabs and how to reach the point of slipping.
